PNEUMATIC STACKER.

SPECIFICATION formingpart of Letters Patent No. 705,407, dated July 1902.

' Application filed April 12, 1902. Serial No. 102,620. (No model.)

To all whom it may concern/:

Be it known that we, EDWARD HUBER and JACOB W. MILLER, citizens of the United States, residing at Marion, in the county of '5 Marion and State of Ohio, have invented certain new and 'usefnl Improvements in Pneumatic Stackers, of which the following is a specification.

Our invention relates to pneumatic straw- IO stackers to be used on threshing-machines and the like, and has for one of its objects to provide a shield to cover the chain or other mechanism employed to lengthen the stacker to prevent pieces of straw clogging the chain.

Another object of our invention is to provide means for normally holding the hood thrown back, so as to allow free egress of the straw from the mouth of the stacker and also to furnish means to throw said hood over said delivery end at any desired angle and to swing the mouth of the stacker in any direction desired.

The advantages of our invention will more fully appear hereinafter and by reference to the accompanying drawings, in which Figure l is a'longitudinal view, partly in section, of our invention; Fig.2, a cross-section of same on the line'2 2of Fig. 1, and Fig.

3 a detailview of-the delivery end of the stacker and t'he'movable hood,

Referring to th'e drawings, in which simi:

lar reference characters indicate correspond-.

ing parts throughout the several views, A represents the tube that is attached to the thresh ing-machine, and B the, delivery-tube that fits over the tube A and is adapted for longitudinal adjustment thereon.

0 represents a shaft journaled in a bracket D, secured near the receiving end of the tube A, the shaft 0 having keyed thereto a sprocketwheel E and a pulley F, said pulley being adapted to be actuatedby a belt running from a pulley on the'threshing-mach'ine or may be turned manually by'means'of a handle. (Not shown.)

a bracket H, secured at the outer end of tube A, and I a chain connecting the two sprocketwheels E and G. The tube 13 is formed with a boxing J to inclose the chain I to prevent pieces of straw getting tangled in the chain G represents a sprocket-wheel'journaled on and sprocket-wheel G andimpa'iring its usefulness.

1 represents a bolt running through a link of the chain I and the top of the boxing J to cause the tube B to slide on thetube A when the chain 1 is actuated by means of the pulley Fand sprocket-wheel E.

, The delivery endKof the tube B is formed separate from said tube and has a flange L, that seats against a flange M on said tube B, the two'flanges being held together by means of clamps N, secured to the tube B; This structure permits the end K tobe swung in any direction desired by means of ropes O, secured to a pin P on the side of the end K and passing around the end K and pulleys Q, journaled in aboxing R on the end of the bracketS, secured to the tube B.

T representsa hood hinged to the delivery end K and held normally thrown back from said delivery end K by ineansof a convolute spring U,'coiled around the pintle V of the hinge and having its ends extended and secured toubrackets WV and W, secured to the end K and hood T.

X represents arope secured to the lower end of the hood T, which is adapted to swing the hood downward to deflect the straw as de= sired.

Having thus described our invention, what we claim is- 1. In a pneumatic stacker, telescoping tubes and a boxing on the slidable tube to cover the means for operating the movable tube, substantially as' shown and described.

2. In a pneumatic stacker, a tube connected to a threshing-machine or other suitable machinery, av tube surrounding said tube and adaptedfor longitudinal adjustment thereon, means to actuate said adjustable tube, and a boxing on said movable tube to cover said actuatin g means, substantially as shownand described. p v

3 In a pneumatic stacker, a hoodhinged to the delivery end thereof, and'afcoil-spring wrapped aroiind the 'pintle of thehinge and having its free ends sec'uied tothehood and delivery" end respectively, substantially as shown and described.

4. In a pneumatic stacker, telescoping tubes, a boxing on the slidable tube to cover the means for operating the movable tube, a hood hinged to the delivery end of said movable tube, and means to normally hold said hood thrown back from the mouth of said delivery end, substantially as shown and described.

5. In a pneumatic stacker, a tube connected to a threshing-machine, a tube surrounding said tube and adapted for longitudinal adjustment thereon, means to actuate said adjustable tube, a boxing on said movable tube to cover said actuating means, a hood hinged to the delivery end of said outer tube, and a coil-spring wrapped around the pintle of the hinge and having its free ends secured to the hood and delivery end respectively, substantially as shown and described.

6. In a pneumatic stacker, a tube connected to a threshing-machine, a tube surrounding said tube and adapted for longitudinal adjustment thereon, brackets mounted at the ends of said stationary tube, a sprocketwheel journaled in each bracket, an endless chain running around said sprocket-wheels, means to actuate said chain, aboxing on said movable tube to inclose said chain, a bolt connecting a link in said chain with said boxing, the delivery end of said movable tube formed separate from said tube and adapted to swing thereon, a hood hinged to said delivery end, and a coil-spring wrapped around the pintle of the hinge and having its free ends secured to the hood and delivery end respectively, substantially as shown and described.

In testimony whereof we hereto afiix our signatures in the presence of two witnesses.
